Analysis of the Manufacturing Process of Plastic Bottle Caps
1. Raw material selection: the basis for ensuring the performance of bottle caps
Choosing the right material is the first step to ensure the quality of bottle caps, and different application scenarios determine the choice of materials.
Common material types:
-
PP (polypropylene): has good heat resistance and chemical resistance, and is often used in carbonated beverages and mineral water bottle caps.
-
HDPE (high-density polyethylene): has high strength and good toughness, suitable for dairy and pharmaceutical bottle caps.
-
LDPE (low-density polyethylene): has flexibility and sealing properties, and is mostly used for soft bottle caps or medical packaging.
Material properties:
-
High temperature resistance: ensure that the bottle cap does not deform during high-temperature sterilization.
-
Corrosion resistance: prevents reaction with the contents to ensure safety.
2. Production process: precision manufacturing to ensure quality
The production of plastic bottle caps mainly relies on two processes-injection molding and compression molding. Choose the appropriate process according to different needs.
Injection molding:
The heated and molten plastic material is injected into the mold and the bottle cap is formed after cooling.
-
Features: fast production speed, precise size, suitable for mass production.
-
Application: Mainly used for the production of bottle caps for water bottles, beverage bottles, etc.
Compression Molding:
The material is compressed and molded by heating the mold, which is suitable for the production of bottle caps with complex structures.
-
Features: Reduce internal stress during the production process, and the bottle caps are more resilient and airtight.
-
Application: Suitable for high-demand sealed bottle caps, such as carbonated beverage bottle caps.
Automated Packaging:
The formed bottle caps are automatically inspected, assembled and packaged to improve production efficiency.
- Steps: The defective products are screened by the visual inspection system, and the packaging is automatically classified to ensure the qualified rate of the products shipped.
3. Quality Control and Inspection Standards: Ensure the safety and reliability of bottle caps
Strict quality control runs through the entire production process to ensure that the bottle caps meet industry standards.
Bottle Cap Size Inspection:
- Use high-precision measuring equipment to check the diameter, thickness and sealing ring size of the bottle cap to ensure that it matches the bottle mouth.
Sealing Test:
- Through vacuum or air pressure testing, verify the tight fit between the bottle cap and the bottle mouth to prevent leakage.
Torque test:
- Detect the opening and closing torque of the bottle cap to ensure that the bottle cap is neither easy to loosen nor too tight when rotating to affect the user experience.
Heat and pressure resistance test:
- High temperature and high pressure tests are performed on hot filling bottle caps to ensure stable performance under harsh conditions.
4. Cost control and environmental protection trends
-
Energy saving and consumption reduction: By optimizing injection molding parameters and compression molding processes, material loss can be reduced and production efficiency can be improved.
-
Sustainable materials: More and more companies are beginning to use recyclable materials (such as PCR) for bottle cap production to comply with environmental protection policies and market demands.

Factors Affecting the Price of Plastic Bottle Caps
1. Fluctuation of raw material prices
The main raw materials of plastic bottle caps are polypropylene (PP) or polyethylene (PE), and the price fluctuations of these materials will directly affect the cost of bottle caps.
-
Oil price fluctuations: As an upstream product of plastic raw materials, changes in international crude oil prices will directly affect the cost of plastic particles.
-
Market supply and demand changes: When the supply of raw materials is tight or the demand increases, prices tend to rise, and vice versa.
-
The impact of environmentally friendly materials: In recent years, some companies prefer to use degradable or environmentally friendly materials, which are usually more expensive and will also affect costs.
Suggestions: Pay attention to the market conditions of raw materials, lock in prices with suppliers in advance, and reduce the risk of cost fluctuations.
2. Mold design and complexity
The design of the mold directly determines the difficulty and precision of the bottle cap production, and also has an important impact on the final price.
-
Mold complexity: Designing precision, multi-cavity molds, bottle caps with anti-theft rings or special functions requires higher mold costs and processing time.
-
Mold life: High-quality molds have a longer service life and lower costs amortized to each bottle cap, while low-quality molds are frequently maintained, increasing hidden costs.
-
Customized design: Bottle cap molds for specific brands or functions require additional development costs, especially when they have unique patterns, logos or special leak-proof structures.
Recommendation: Choose an experienced mold manufacturer to ensure mold quality and production stability, and reduce long-term operating costs.
3. Batch order size and customization needs
The order size has a significant impact on the unit price of plastic bottle caps. Large-volume orders can often dilute fixed costs, thereby reducing unit prices.
